FlintBoard™ ISO-T Plus

FlintBoard ISO-T Plus tapered composite polyisocyanurate/perlite roof insulation is manufactured in a tapered profile to offer the combination of high thermal values plus promotion of proper roof drainage. As with regular ISO Plus, FlintBoard ISO-T Plus features closed-cell polyiso bonded to a 1/2" perlite with a fiber reinforced felt facer on the bottom.

FlintBoard ISO-T Plus is offered in a variety of tapered panels, providing average long-term thermal resistance (LTTR) values from 5.9 to 15.1. Higher LTTR values can be achieved with layers of flat FlintBoard ISO. Available in 4' x 4' (1220mm x 1220mm) panels only.

Before installation begins, the roof deck must be firm, well attached, even, clean and dry.

Do not leave exposed. FlintBoard ISO-T Plus is a polyiso organic plastic foam and will burn if exposed to an ignition source of sufficient heat and intensity, or open flame, such as a welder's torch. Do not apply flame directly to FlintBoard roof insulations.
